CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. application Ser. No.12/538,622, filed Aug. 10, 2009, the disclosure of which isincorporated, in its entirety, by this reference.

BACKGROUND

Enterprises and individuals periodically upgrade or replace securitysoftware products that protect their computing systems. Variousconventional technologies may be used to upgrade and replace securitysoftware products. Unfortunately, conventional technologies forupgrading and replacing security software products, such as MICROSOFTINSTALLER (“MSI”) and MICROSOFT PATCH (“MSP”) technologies, may leave acomputer system vulnerable during a time period when no security productis running.

MSI replacements of security products often involve uninstalling anexisting security product, rebooting a computing system on which thesecurity product was installed, and installing a new security product.The computing system may be unprotected from the time the old securityproduct was uninstalled until the time the new security product isinstalled and activated.

MSP upgrades of security products may transform a first version of asecurity product to a second version of a security product. During theupgrade, running processes of the security product may be stopped,updated, and then restarted. Thus, the system protected by the securityproduct may be vulnerable while the security product is being updated.What is needed, therefore, is a more effective way to replace and/orupdate software products.

Rather, theinstant disclosure covers all modifications, equivalents, andalternatives falling within the scope of the appended claims.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

As will be described in greater detail below, the instant disclosuregenerally relates to systems and methods for updating a softwareproduct. Embodiments of the instant disclosure may over-install a newproduct without uninstalling an existing product during the installationprocess. For example, a computing system may install a second version ofa software product in a dormant state while a first version of thesoftware product is running and may swap the first and second versionsof the software product by activating the second version of the softwareproduct and deactivating the first version of the software product.

Embodiments of the instant disclosure generally apply to situationswhere a software product is being installed over another softwareproduct (i.e., situations where only one version of a product can run ata time). In such situations, conventional installation tools typicallyuninstall the existing software product before installing the newsoftware product, which may result in a period of time when neithersoftware product is running. For security software products, such asantivirus and data protection products, a computing system protected byan existing product may be vulnerable while the existing product isuninstalled and a new product is installed. Embodiments of the instantdisclosure may eliminate and/or minimize down time of a software productby installing a new version of the software product while an existingversion of the software product is still running. Embodiments of theinstant disclosure also provide various other features and advantages.

The following will provide, with reference to FIGS. 1-2, detaileddescriptions of exemplary systems for updating a software product.Detailed descriptions of corresponding computer-implemented methods willalso be provided in connection with FIGS. 3 and 4.

FIG. 1 is a block diagram of an exemplary system 100 for updating asoftware product. As illustrated in this figure, exemplary system 100may include one or more modules 102 for performing one or more tasks.For example, and as will be explained in greater detail below, exemplarysystem 100 may include an interface module 104 programmed to receive arequest to install a second version of a software product over a firstversion of the software product. Exemplary system 100 may also includean installation module 106 programmed to install the second version ofthe software product in a dormant state while the first version of thesoftware product is running.

In addition, and as will be described in greater detail below, exemplarysystem 100 may include a swapping module 108 programmed to swap thefirst and second versions of the software product by deactivating thefirst version of the software product and activating the second versionof the software product. Although illustrated as separate elements, oneor more of modules 102 in FIG. 1 may represent portions of a singlemodule or application.

In certain embodiments, one or more of modules 102 in FIG. 1 mayrepresent one or more software applications or programs that, whenexecuted by a computing device, may cause the computing device toperform one or more tasks. For example, as will be described in greaterdetail below, one or more of modules 102 may represent software modulesstored and configured to run on one or more computing devices, such asthe devices illustrated in FIG. 2 (e.g., computing device 202 and/orserver 206), computing system 510 in FIG. 5, and/or portions ofexemplary network architecture 600 in FIG. 6.

As illustrated in FIG. 1, exemplary system 100 may also include one ormore databases 120. Databases 120 may represent portions of a singledatabase or computing device or a plurality of databases or computingdevices. In one embodiment, exemplary system 100 may include adifferences database 122 for storing differences between a first versionof a software product and a second version of the software product.Exemplary system 100 may also include a settings database 124 forstoring one or more settings to be migrated from a first version of asoftware product to a second version of the software product.

Databases 120 in FIG. 1 may represent a portion of one or more computingdevices. For example, databases 120 may represent a portion of server206 in FIG. 2, computing system 510 in FIG. 5, and/or portions ofexemplary network architecture 600 in FIG. 6. Alternatively, databases120 in FIG. 1 may represent one or more physically separate devicescapable of being accessed by a computing device, such as server 206 inFIG. 2 computing system 510 in FIG. 5 and/or portions of exemplarynetwork architecture 600 in FIG. 6.

Exemplary system 100 in FIG. 1 may be deployed in a variety of ways. Forexample, all or a portion of exemplary system 100 may represent portionsof a cloud-computing or network-based environment, such as exemplarysystem 200 illustrated in FIG. 2. Cloud-computing environments mayprovide various services and applications via the Internet. Thesecloud-based services (e.g., software as a service, platform as aservice, infrastructure as a service, etc.) may be accessible through aweb browser or other remote interface. Various functions describedherein may be provided through a remote desktop environment or any othercloud-based computing environment.

As shown in FIG. 2, system 200 may include a computing device 202 incommunication with a server 206 via a network 204. In one embodiment,computing device 202 may include one or more of modules 102 and/or oneor more of databases 120. Computing device 202 may also include a firstversion of a software product 220 and a second version of the softwareproduct 222. Computing device 202 may execute one or more of modules 102and may use one or more of databases 120 in a process for writing secondversion of the software product 222 over first version of the softwareproduct 220. In some embodiments, computing device 202 may receivesecond version of software product 222 from server 206 as part of anenterprise software deployment. Alternatively, second version of thesoftware product 222 may be written over first version of the softwareproduct 220 as part of an installation initiated directly on computingdevice 202. For example, second version of the software product 222 maybe provided by any suitable delivery mechanism, including a CD, a DVD, aBLUERAY disk, a USB device, the Internet, and/or a local network.

Computing device 202 generally represents any type or form of computingdevice capable of reading computer-executable instructions. Examples ofcomputing device 202 include, without limitation, laptops, desktops,servers, cellular phones, personal digital assistants (PDAs), multimediaplayers, embedded systems, combinations of one or more of the same,exemplary computing system 510 in FIG. 5, or any other suitablecomputing device.

In one embodiment, network 204 may facilitatecommunication between computing device 202 and server 206.

FIG. 3 a flow diagram of an exemplary computer-implemented method 300for updating a security software product. The steps shown in FIG. 3 maybe performed by any suitable computer-executable code and/or computingsystem. In some embodiments, the steps shown in FIG. 3 may be performedby one or more of the components of system 100 in FIG. 1 and/or system200 in FIG. 2. For example, at step 302 interface module 104 may, aspart of computing device 202, receive a request to install a secondversion of a software product over a first version of the softwareproduct. In some embodiments, the request may be received from a remoteapplication. For example, a server deploying the second version of thesoftware product may request installation of the software product. Therequest may also be a request from an installation package that containsthe second version of the software product. Additionally oralternatively, the request may be received from an InformationTechnology (“IT”) administrator or other user.

As used herein, the phrase “software product” refers to any softwareapplication, executable file, installation package, or othercomputer-executable code programmed to be installed and executed on acomputing system. Software products include, without limitation, wordprocessors, spreadsheets, productivity software, security software(antivirus programs, firewalls, parental-control software,data-loss-prevention software, etc.), and various other types ofsoftware programs. The phrases “first version of a software product” and“second version of a software product” may refer to older and newerversions, respectively, of the same software program from the samecompany. For example, the first version of a software product may be a2008 version of an anti-virus program and the second version of thesoftware product may be a 2009 version of the same program.

Alternatively, the first and second versions of a software product maybe different programs that perform similar functionality. For example,the first version of a software program may be a firewall applicationdeveloped by a first software company and the second version of thesoftware program may be a firewall application developed by a secondsoftware company. In other embodiments, the first and second versions ofa software program may be different, but related, programs from the samecompany. For example, the first version of the software product may be abasic computer security program with basic functionality (e.g., anantivirus program) and the second version of the software product may bean advanced computer security program with more advanced functionality(e.g., an internet security suite of programs).

As used herein, the phrase “install a second version of a softwareproduct over a first version of the software product” generally refersto over-installing one version of a software product over anotherversion of the software product. An over-install generally refers to aninstallation process for installing one version of a softwareapplication and removing a previous version of the software application.In contrast, other installation processes may not involve replacing oneversion of a product with another version of the product. Suchinstallation processes include installing a patch to an existingsoftware product and installing two versions of a software productside-by-side. Over-install does not refer to these patch installationsand side-by-side installations.

Over-installation processes may be used in situations where only asingle instance of a software product may run at a time. For example,many computing systems may only allow one firewall software program torun at a time. Other single-instance install situations includesituations where installation of two similar software products mayresult in conflicts and/or other issues that may result in systeminstability.

Returning to FIG. 3, at step 304 installation module 106 may, as part ofcomputing device 202, install the second version of the software productin a dormant state while the first version of the software product isrunning. Installation module 106 may install the second version in avariety of manners, as described in greater detail below. As usedherein, the phrase “dormant state” refers to a software product that isat least partially installed but is not executing. Installation module106 may install the second version of the software product in a dormantstate by installing the second version of the software product in amanner that does not interfere with the first version of the softwareproduct as the first version of the software product is running.

In some embodiments, installation module 106 may install the secondversion of the software product by installing one or more files of thesecond version of the software product. For example, installation module106 may install one or more executable files and/or other code of thesecond version of the software product. Installation module 106 may alsoinstall one or more other components of the second version of thesoftware product. For example, installation module 106 may install oneor more services, drivers, registry keys, and/or other components of thesecond version of the software product.

Installation module 106 may partially install the second version of thesoftware product by only installing files and other components of thesecond version of the software product that do not affect execution ofthe first version of the software product and by refraining frominstalling one or more components of the second version of the softwareproduct that may affect execution of the first version of the softwareproduct if installed. Installation module 106 may identify components ofthe second version of the software product that do not affect executionof the first version of the software product in a variety of ways. Insome embodiments, installation module 106 may identify such componentsby reading a list or other database that identifies components that aresafe to install while the first version of the software product isrunning.

In other embodiments, installation module 106 may automatically identifyone or more components of the second version of the software productthat are safe to install by determining whether the first version of thesoftware product is utilizing components that correspond to the newcomponents. For example, installation module 106 may refrain fromoverwriting a driver that is currently being used by the first versionof the software product.

According to certain embodiments, installation module 106 may identify aset of differences between the first and second versions of the softwareproduct. The set of differences may be a list, a differential file, aninstruction set, and/or any other set of information that identifies oneor more differences between the first and second versions of thesoftware product. The set of differences may identify one or moreregistry keys, one or more services, one or more shortcuts, and/or oneor more actions that need to be performed at a later point in time(e.g., after a reboot) to swap the first and second versions of thesoftware product. The set of differences may additionally oralternatively identify one or more registry keys, one or more services,one or more shortcuts, and/or one or more actions that may be performedwhile the first version of the software product is running (i.e.,actions that will not affect execution of the first version of thesoftware product, as previously discussed).

Installation module 106 may save one or more settings of the firstversion of the software product. For example installation module 106 mayread one or more settings of the first version of the software productand save the settings in a database, such as settings database 124.Swapping module 108 may then read the settings from the database andimport the settings into the second version of the software product.Thus, one or more settings of the first version of the software product,such as user-defined settings and/or other settings, may be preserved inthe second version of the software product.

After the install is complete (or before or during the install),installation module 106 may register a service that will swap the firstand second versions of the software product. The registered service,which may include swapping module 108, may be an executive mode process(i.e., a chkdsk process), a kernel driver, a system service, and/or anyother suitable service.

At step 306, swapping module 108 may, as part of computing device 202,swap the first and second versions of the software product. Swappingmodule 108 may swap the first and second versions of the softwareproduct in a variety of manners. For example, swapping module 108 mayswap the first and second versions of the software product by activatingthe second version of the software product and deactivating the firstversion of the software product. As used herein, the phrase “activatingthe second version of the software product” generally refers to anyprocedure that causes one or more processes of the second version of thesoftware product to run and/or prepares one or more processes of thesecond version of the software product to run. Conversely, the phrase“deactivating the first version of the software product” generallyrefers to any procedure that causes one or more processes of firstversion of the software product to stop executing, prepares the firstversion of the software product to terminate execution, and/or modifiesthe first version of the software product such that the first version ofthe software product will not restart after being terminated.

In some embodiments, swapping module 108 may, while the first version ofthe software product is running, modify a state of one or morecomponents of the first version of the software product such that theone or more components will not restart after a reboot. For example,swapping module 108 may change the state of one or more services and/ordrivers in the first version of the software product such that they donot run after a system reboot.

Swapping module 108 may use a previously identified set of differencesbetween the first and second versions of the software product to updateone or more components of the first version of the software product foruse with the second version of the software product. For example,swapping module 108 may update one or more registry keys of the secondversion of the software product (e.g., by adding new keys, deleting oldkeys and/or modifying existing keys). Additionally or alternatively,swapping module 108 may update (e.g., add, delete, and/or modify) someor all services and/or drivers of the second version of the softwareproduct. Swapping module 108 may also update one or more shortcuts,including symbolic links, of the second version of the software product.Swapping module 108 may further run one or more custom actions, such ascustom executables that may modify the computing system outside of theinstall process.

According to certain embodiments, swapping module 108 may uninstalland/or otherwise cleanup the first version of the software product afterthe first version of the software product is deactivated and the secondversion of the software product is activated. For example, swappingmodule 108 may remove any files and other data associated with the firstversion of the software product.

FIG. 4 is a flow diagram of another exemplary computer-implementedmethod for updating a security software product, such as an antivirusapplication, a firewall application, a data-loss-prevention application,and/or any other application for protecting a computing system and/ordata stored on a computing system. The steps shown in FIG. 4 may beperformed by any suitable computer-executable code and/or computingsystem. In some embodiments, the steps shown in FIG. 4 may be performedby one or more of the components of system 100 in FIG. 1 and/or system200 in FIG. 2. For example, at step 402 interface module 104 may, aspart of computing device 202, receiving a request to install a secondversion of a security software product over a first version of thesecurity software product. At step 404, installation module 106 mayinstall one or more components of the second version of the securitysoftware product that do not affect execution of the first version ofthe security software product. Steps 402 and 404 are similar to steps302 and 304 and may be performed in one or more of the manners describedin FIG. 3.

At step 406, installation module 106 may modify a state of one or morecomponents of the first version of the software product such that theone or more components will not restart after reboot. For example,installation module 106 may modify one or more services and/or driversof the first version of the software product such that they do not runafter a system reboot. Such a process may be particularly useful forservices and/or drivers that cannot be unloaded and/or stopped.Alternatively, services and drivers may not need to be modified before areboot if an executive mode process is used to update services and/ordrivers before they are allowed to start after reboot.

At step 408, installation module 106 may cause a computing systemprotected by the first version of the software product to reboot. Insome embodiments, the rebooting may be performed after installing thesecond version of the software product and before activating the secondversion of the software product. In some embodiments, to protect thecomputing system from security threats, the second version of thesoftware product may be activated during the rebooting process beforeone or more network adapters of the computing system are enabled. Forexample, swapping module 108 may cause the second version of thesoftware product to be activated early in a boot process (i.e., beforenetwork adapters are activated). Alternatively, swapping module 108 maydisable one or more network adapters of the computing system until thesecond version of the software product is enabled. Swapping module 108may also perform any other suitable action to protect the computingsystem while the first and second versions of the software product arebeing swapped.

In some embodiments, the first version of the software product may notbe disabled immediately after a reboot. For example, security driversfrom the first version of the software product may run after a firstreboot (e.g., such as antivirus and/or firewall drivers). During thefirst reboot, an executive mode application may run, which may updateone or more components of the first version of the software product tothe second version of the software product. For example, the executivemode application may be re-pointed without affecting their currentinstance. The operating system of the computing system may not be fullyfunctional (i.e., fully loaded after the first reboot). The softwareproduct may not be fully loaded after the reboot either. After thecomponents of the first version of the software product are updated, thefirst version of the software product may be set to be disabled and thesecond version of the software product may be enable a set to run aftera second reboot. The executive mode application may force a secondreboot at this point. In such situations, the first version of thesoftware product may continue to run until after the second reboot.

At step 410, swapping module 108 may swap the first and second versionsof the security software product. Step 410 is comparable to step 306 inFIG. 3. Thus, one or more of the processes disclosed in the discussionof step 306 may also be used to perform step 410.

Embodiments of the instant disclosure may enable installation of a newversion of a security product over an existing version of the securityproduct in a manner that does not expose a computing system tovulnerabilities. For example, installation processes described hereinmay be performed such that there is no down time between deactivating afirst security software application and activating a second securitysoftware application.
